This invention relates to a sterile packing for dressings, consisting ofa compress folded up and having attaching means, enclosed in an envelopeadapted to be torn. Several forms of construction of such packings forcompresses have become known. Some of these packings are arranged sothat the envelope can be easily torn without the aid of a tool, theremoving of the sterilized compress being however left absolutely to theskill of the user and to the careful handling by the same. ln packingsof other types the compress is folded and sewn together or it hasholding means on the rear side so that it must be gripped with bothhands, torn open or spread out. 7

All packings of known type require therefore complicated manipulationswhen they are being made ready for use so that, even at the most carefulhandling, the compress might be touched, not to mention that touching ofthe rear side of the compress is also dangerous.

This invention relates to a sterile packing for dressings, which isconstructed so that the compress can be removed from the packing withoutbeing touched, even if not handled carefully, and with one grip.

In this packing the ends of holding threads of the compress project intoan empty portion of the wrapper designed to be torn off, said holdingthreads being clamped in stretched position in this empty portion of thewrapper or envelope so that the ends of the holding threads are grippedtogether with the portion of the wrapper to be torn off or project fromthe wrapper after the empty portion of the same has been torn ofl, sothat the compress can be removed from the wrapper and spread out bymeans of these holding threads.

An embodiment of the invention is shown, by way of example, in theaccompanying drawing, in which Fig. 1 shows the dressing material in theform of a compress in top plan view in spread out state.

Fig. 2 shows in top plan view a compress half folded.

Fig. 3 shows the compress shown in Fig. 2

enclosed and in top plan View in the wrapper. Fig. 4 is an end elevationof the wrapper with compress, the end of the wrapper being torn off. i

Fig. 5 shows in longitudinal section a wrapper with compress.

The compress a designed for dressinga wound consists of sterile notimpregnated gauze, cotton wool or other dressing material, and it hastwo holding threads or holding bands Z). The 1 compress a is forinstance folded four times in the longitudinal direction and. theholding threads, sewn in the two lateral edges at the middle of thesame. are arranged at the packing so that their ends project from atransverse edge of the folded compress, as shown in Figs. 3 and 5.

The wrapper or envelope is made of a material which can be torn,preferably paper, which after the compress has been wrapped is closed atboth ends by folding and by means of clamps (Z, the wrapper beingairtightly closed by a cover.

The envelope is preferably longer than the compress and this compress isinserted so that the holding threads projecting from the transverse edgeextend into an empty portion of the wrapper which is designated as thepiece to be torn off for instance by a red line 0.

The envelope is of such dimensions that the dressing material is held inthe same with slightpressure so that it cannot shift, and the emptyportion 0 of the wrapper or envelope is strongly pressed together at thepacking so that the threads in this portion are held in stretchedposition between the walls of the envelope as shown in Figs. 3 and 5.

hen the empty portion 0 of the envelope designated by the line 6 is tornoff, the holding threads 6 are held between the fingers, to-

gether with the torn of portion of the envelope, or they are liberatedand project from the open end of the envelope as they have become stiffby the sterilizing.

The ends of the two threads 6 are preferably tied in knots and grippedbetween the fingers with the hand so that the compress can be pulled outof the wrapper without having touched and even without coming intocontact with the torn edge of the envelope. The latter fact is veryimportant as, if the open edge of the wrapper has been in fected withgerms by the hand, these germs will be transferred to the sterilecompress when it moves along the open edge at being pulled out of theWrapper.

To unfold the folded compress, one of the holding threads is grippedwith the other hand and the compress is placed on the wound by means ofthe two threads in the unfolded state as shown in Fig. 1.

Two holding threads might evidently be attached to each side of thecompress, and one pair of the threads'might project from one.

transverse edge of the compress the other pair of threads projectingfrom the other transverse edge of the compress, both ends of the wrapperbeing then preferably provided with a piece to be torn off.

I claim A. sterile packing for dressings, comprising in combination witha dressing for wounds, an envelope of paper enclosing said dressing andhaving a tear-off portion for the removal of said dressing, saiddressing having a holding thread for spreading said dressing in thelongitudinal centre of each side edge and being folded with these sideedges inwards and the ends of the holding threads placed in the tear offportion of the envelope, knots on the ends of said holding threads, ametal strip adapted to press flat the tear off portion of said envelopeto hold the ends of the holding threads and to release said threads whensaid tear off portion is removed.

In testimony whereof I aflix my signature.

ERNST BLANK.
